Title: Time calculator
Inventor: SUGA FUSAO
IPC: A63B71/06
Filed: 1993-07-13
Abstract: PURPOSE:To predict time required for an arbitrary motion by providing means for measuring biological information at the time of motion and inputting/storing the motion amount data, and means for operating/outputting a predictive time. CONSTITUTION:When a runner reaches the goal and a goal switch SW2 is turned on, a measurement of running time is stored. When the runner places his finger on a pulse detecting section 4, a light emitting element and a light receiving element 6 detects pulse and a control section calculates the number of pulses. The runner repeats running and measurement of pulse several times, and the running time and the number of pulses are stored for each trial. When a running distance is inputted and stored, running speed and the number of pulses are stored for each trial and a regression line is determined based on the measurements and then stored in a regression line register. Age is then inputted on a key K1 and a predictive running speed is calculated and stored in a register. Subsequently, switching is made to goal time display mode through a switch SW 3 and when a running distance is inputted on a key K2, a predictive goal time is determined based on the running distance thus inputted and a predictive running speed stored in the register and thus determined predictive goal time is displayed.

Next, when the thermal body is cooled, it returns to the first cloudy opaque state. Therefore, by selectively applying heat to the thermal body, the thermal body is selectively heated and a cloudy image or cloudy opaque image can be formed on a transparent background and said change can be repeated many times.

Title: Bypass-valve warming apparatus for turbine
Inventor: ASANO HIROYUKI
IPC: F01D25/10
Filed: 1982-11-08
Abstract: PURPOSE:To soften thermal impact by detecting the difference between the temperature of the steam in a steam chamber on the upstream side of a turbine bypass valve and the temperature of the metal of a steam chamber on the downstream side by a temperature-difference detector and opening and closing controlling a control valve in a warming steam pipe, according to the detection signal. CONSTITUTION:The temperature detecting edges 30 and 31 for detecting the temperature of the steam in an upstream-side steam chamber 21 and the temperature of the metal of a downstream-side steam chamber 22 respectively are installed onto the valve casing 20 of a turbine bypass valve, and each signal is input into a temperature difference detecotr 32. With this temperature-difference signal, opening-degree control for the control vavle 34 of a warming-steam feeding pipe 33 is performed through a bypass-valve warming controller 35. Therefore, in ordinary operation, the temperature of the wall, etc. of the downstream- side steam chamber is kept above a certain level, and the thermal impact due to sharp opening of the valve is softened. In testing the bypass valve, opening degree rate in a test demand signal (a) is varied according to the magnitude of the temperature difference signal by a valve test controller 36, and when the temperature difference is large, warming is executed with a minute opening degree, and then the valve is opened perfectly according to the warming state, and thus thermal stress is reduced.

Title: Lead frame
Inventor: SANO YUUJI
IPC: H01L23/50
Filed: 1981-12-07
Abstract: PURPOSE:To improve the wetting property and the bondability of a soldering material by a method wherein punching pattern is changed in such a manner that one of tab lifting sections is punched out so that it is linked with the outer lead extending in the direction different from that opposing to the other  tab suspending section, thereby allowing to reduce the deformation of the tab  lifting section. CONSTITUTION:A tab 11 is formed in such a manner that it will be positioned a little lower than the plane surface of the tab lifting sections 12 and 13. The tab lifting sections are to be punched out in such a manner that one tab lifting section 12 will be linked to a coupled part 10A, and the other tab lifting section 13 will be linked to an outer lead section 19 respectively. Accordingly, the deformation of the tab lifting section in the direction of the arrow A can be prevented effectively because the internal stress of the tab lifting sections 12 and 13 is reduced. The suppression of the deformation in the direction A of the tab lifting sections 12 and 13 allows the tab 11 to maintain an appropriate plane position, and the workability can be greatly improved when pellet attaching and wire bonding works are performed.

Title: Collapsible tube and manufacture thereof
Inventor: TSUCHIDA KATSUSHI
IPC: B62D1/19
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a collapsible tube to have no discontinuous part against strength and rigidity and the excellent absorption efficiency of a shock energy. SOLUTION: A collapsible tube comprises a bellows part 1 consisting of a plurality of large parts 11 and small parts 19; and coupling parts formed in succession to the bellows part 1 and coupled to the other member. The bellows part 1 and the coupling part 2 are integrally molded through various plastic processing means based on a thick section-form hollow pipe made of a metal. Thus, since all parts are formed through the plastic processing means based on a single member, the flow of a material texture is unified in a specified direction and thus, strength and rigidity are uniformized. As a result, the absorption efficiency of shock energy is improved.

Title: Refrigerant feeder
Inventor: NAKANO GENICHI
IPC: F25B45/00
Filed: 1988-08-05
Abstract: PURPOSE:To prevent evaporation of refrigerant and rising of bubbles for performing an accurate reading of liquid level, by providing such a constitution that charging operation is switched by a switching valve, and building a portion of a refrigerant path and a refrigerant transfer pipe into a double pipe construction. CONSTITUTION:A refrigerant transfer pipe 9 is connected to an air conditioner, etc. by a charging hose, etc. Then, a switching valve 8 is switched so as to let a narrow path of the valve face the outlet side. When the refrigerant flows from a charging container 1 through the switching valve 8, a pressure difference is produced between the inlet side and outlet side of the valve because the outlet side is narrowed by the switching valve 8, and the inside of a refrigerant transfer pipe 9 on the outlet side of the switching valve 8 is cooled, causing a refrigerant path 7 to be also cooled due to the double pipe construction. Cooling the refrigerant path 7 by the refrigerant flowing along the refrigerant transfer pipe 9 prevents the occurrence of such a phenomenon that the refrigerant in the refrigerant path 7 is evaporated by receiving heat from the atmosphere and bubbles rise into a liquid level indicator 5 when the liquid level in the liquid level indicator 5 fluctuates. Thus, the refrigerant in the refrigerant path 7 is prevented from evaporating, and re-liquefied. Therefore, the liquid level in the liquid level indicator is prevented from being ruffled because bubbles are prevented from rising through the inside of the refrigerant indicator 5.

CONSTITUTION:An electron beam 8 generated from an electron gun 7 is narrowed to a small diameter of several mum or less through an electromagnetic lens which is not shown. The electron beam is projected on an X-ray generating target 9. Thus, X-rays 10 are generated in the target 9 and projected on a sample 6 through an electron-beam shielding filter 12. The filter 12 is the filter which prevents the input of higher energy electrons reflected from the surface of the target 9 into an X-ray detector 17. The filter is provided between the sample 6 and an X-ray spectral crystal 14 and the like. The X-rays 10 projected on the sample 6 undergoes specific absorption of the sample 6. The X-rays 10 are transmitted through the sample 6 and inputted into the crystal 14. In the crystal 14, the X-rays are diffracted under the Bragg diffraction condition of nlambda=2d.sintheta and undergo spectroscopy. Then, the X rays are inputted into an X-ray detector 17 through a slit 16, and the intensity is measured with an X-ray measuring circuit 18.
